is a evga 450bt good for a system with 3570k and 750ti with cpu at around 4ghz and gpu at around 1500mhz? if not what is some budget recommendation i want to spend around 50 bucks max.

Nothing is really known about it at this point but it's super cheap and I would guess about on-par with their own 80 PLUS White series so I'd say it's fine to power a 750 Ti, I'd just see if you can squeeze a few bucks more and get a better unit. The Corsair CX450/M or EVGA 450B3 should do fine.

Ripple is bad, 15-22mV on 12V Rails

22mV on the 12V is excellent...

Well maybe not bad, but "acceptable, not as good as something like EVGA G3"

 

But it's not 80+Bronze, only white.

...You do realized that ATX specification defines that the 12V rail doesn't exceed 120mV right? As well as the difference between 10mV on the G3 vs 23mV is negligible in the real world? Or that units like the HX750i had seen up to 25mV on the 12V.

 

Saying that it is "acceptable" is a great disservice such those units as well as to units like the Seasonic X KM3 that can hit 40mV. We are at the level of greatly suppress ripples that it just a matter of bragging rights for the company now.

Regardless, the Ultra X4 has rather mediocre ripple suppression in this review as it goes up to 100mV on the 12V. https://www.hardocp.com/article/2009/11/24/ultra_x4_850w_1050w_power_supplies_review/5

The 1200w model did rather poorly as well: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=174

 

So Tweaktown had a golden sample?

It's probably OK but it is rather old. If you want to upgrade a big component like a CPU or GPU it might not be a bad idea to replace it.

 

I think Ultra offers a lifetime warranty if you register the product with them. Not sure how you go about doing that though.

"Wat" on what point?

Paul sample of the 850w had the ripple on the 12V rail going up to 100mV, while Jeremy sample had it going 100mV on the 1200w model as well, but since it lacks OTP, his sample had gone out of specs at 218mV in the hot box. The golden sample comment was referring to how Tweaktown has shown only 23mV figures, despite the other reviewers had right below specs.

Different reviews getting entirely different results was my "wat" point.

Ah, sorry. I got confused. lol

 

But yeah, the difference in reviews was completely opposite that it doesn't seem to cause by simple manufacturer variances or differences in testing methodology. There's a possibility that Ultra had the OEM tweaked it as Tweaktown review was published 6 months after Paul and Jeremy review maybe?

 

Anyways, I believe the Ultra brand is dead (Tiger Direct's house-brand / division of Systemax), when the founder of TD got convicted for fraud. So there is no more warranty on them.

I know this topic is really old, but thank you for it. I bought a 650W EVGA P2 Platinum Power Supply and couldn't be happier.

It gets regularly updated. Many people reply to it. The original list is always updated.

I have the EVGA NEX gold series psu, should I be worried for it's performance or will I be fine for the time being? I thought it was a good power supply being 80+ Gold.

Should be fine for quite a while. What are your full specs?

I would just change it with your next upgrade. If you had a 1080Ti and that i7, I would tell you to upgrade now, but in this case I wouldn't.

 

But don't listen only to me, get advice from @STRMfrmXMN and @Energycore before you proceed.

The NEX-G / G1 is indeed a mediocre PSU, whose design is more suited in the ~550w and below range. Since your setup is peaking around ~250wDC during your typical load (mileage may varied depending on overclocks), you should be fine.

 

Of course, since you haven't built it yet, getting a proper PSU first may be for the best, so you don't have to redo your cable management.

It's just something you shouldn't buy, not something that will blow up tomorrow. You'll be fine. It's just a bit of a mediocre performer (it is group-regulated) and is at a price point comparable to much better EVGA units.

If you haven't built, return it.

Yeah, that's a huge red flag any time I see it. Especially after the CM GX650 I had at the time killed 2 graphics cards on me because of poor group regulation (actually failed cross load tests during johnny guru's review). I will never touch another group regulated unit again. lol

Possibly silly question… How does one tell for sure if a particular PSU is group-regulated or …whatever the alternative is? I don't think I've ever noticed that in a PSU's consumer-facing technical specs, so is it just something you have to find out from reviews?

The only way I've been able to confirm is by reading reviews from reputable sources like johnny guru. I believe most modern gold+ rated high-quality PSUs have individually regulated rails. It's usually the lower-end units that are group regulated and generally struggle when it comes to cross-loading. 

 

If there is another way to identify this, I'd like to know as well.

I mean, I'd still suggest a Seasonic S12 to many people so it's not all bad news.
